Marinco CS504-25 EEL 50A 125V/250V Shore Power Cordset - 25' - Yellow

The Marinco CS504-25 EEL 50A 125V/250V Shore Power Cordset with 25-foot cable delivers one-handed connection and disconnect at the boat dock. The EEL (Easily Engaged Lock) design features a jaw-clamp mechanism that eliminates the traditional locking ring entirely, replacing it with a secure waterproof seal built for saltwater environments. This cordset carries UL approval and is engineered for the demanding conditions boaters face—salt spray, moisture, and repeated connection cycles that degrade standard shore power cables over time.

The 50-amp, 125/250-volt rating supports full-power shore power on modern cruising boats and larger recreational vessels that rely on dual-voltage systems for air conditioning, water heating, and galley appliances. The 25-foot length provides standard dock reach without excess coiling, reducing voltage drop across the cable while keeping the cordset manageable for stowage. A built-in cord light serves as a visual alert, helping boaters confirm the connection is live and preventing accidental disconnection during refueling or crew movement on the dock. The yellow jacket improves visibility in low-light docking conditions and provides abrasion resistance against dock hardware and fender contact.

This cordset is built for weekend cruisers and serious offshore operators alike who dock frequently and demand reliable power without fumbling with locking rings or wrestling with corroded connectors. The one-handed operation matters when you're alone at the helm managing docklines or when deck space is tight. Boaters who've upgraded from standard cordsets appreciate the durability advantage—jaw-clamp designs don't develop ring corrosion that leads to poor electrical contact and potential fire hazard, a common failure mode in traditional designs exposed to salt air.
